energy of motion
kinetic energy
energy associated with the position of an object and the forces acting upon it
potential energy
energy from motion or forces that affect a whole object
mechanical energy
consists primarily of energy caused by internal motion and forces at the atomic and molecular level

for the properties of matter to change, energy
must be either ______or _____
transferred from one object to another
changed from one form to another
the energy lost by one object equals the energy gained by the other
law of conservation of energy
fundamental to physical science
law of conservation of energy
discovered that mass and energy can be considered two different ways of measuring the same physical property
Albert Einstein
the relationship between mass and energy
mass-energy equivalence
the relationship between mass and energy described in an equation from a German physicist
